About this tool

The JSON-LD Schema Validator checks that your structured data is valid JSON and that it carries the two fields every schema block needs: @context and @type.

Frequently asked questions

Does valid JSON mean valid schema?

No — it means the syntax parses. Type-specific rules (required properties) need a dedicated schema validator.

What is @context?

It declares the vocabulary — almost always https://schema.org.
